What it does
LTX Workflow is a comprehensive resource hub for creating AI videos with LTX 2.3 and ComfyUI. 🎬 What you get: • Step-by-step tutorials for text-to-video, image-to-video, and motion control • Ready-to-use ComfyUI workflow files • Model comparison and optimization guides • Hardware requirements and performance tips • Community showcase and research updates
Match your VRAM, download LTX 2.5 (Gemma 4, gated) or LTX 2.3 (FP8 + taeltx2_3.safetensors + Gemma 3), grab the right ComfyUI workflow JSON, or run i2v online — no GPU needed.
Stuck on a missing taeltx2_3.safetensors , an out-of-memory error, or the wrong checkpoint for your GPU? Pick a model family and your VRAM — LTX 2.5's gated Gemma 4 files need 24GB+ unless you use the GGUF path, LTX 2.3's FP8 fits 16GB — get the exact files you need, and generate a ready-to-import ComfyUI workflow JSON for LTX 2.3 in under 2 minutes. T2V, I2V, LoRA, and spatial upscaler all supported. LTX 2.3 FP8 (16GB) and official distilled & dev (24–32GB), plus LTX 2.5's gated Gemma 4 + INT8 convrot files (24GB+) or the community GGUF path for 16GB. Official workflow JSON files from Lightricks — T2V, I2V, two-stage upscaler, ICLoRA motion tracking. Drag into ComfyUI to load. Answer a few…from ltxworkflow.com

LTX.bio2021 · lightricks.com · ▲164Hey HN, after our 13B release we've been working on a faster version of our open-source video model and we're excited to share it. We started with a 13B base model that already had competitive generation speeds (e.g. 55s for a 5s video on an H100 — faster than any other model out there). But we wanted to push it further to allow everyone to quickly iterate over their video generations. So we built a distilled version focused on speed without sacrificing temporal or spatial coherence. With the Distilled model, you can now generate 5-second 720p videos in about 9.5 seconds on an H100, and…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
